y SPECIFICATION forming part of VLetters Patent No. 284,144, dated'August 28, 1883..

` Application flied april 19, 1883. (No moaei.) i.

siding at Chapman, in the county of Merrick and State of Nebraska, have invented certain new and useful Improvements in RailroadlSwitch Stands, and I do hereby declare the following to be a full, clear, and exact description ofl the invention, such as will enable others,

skilled in the art to which it appertai'ns to make and use 'the saine, reference being had to theaccompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention consists in certain new and useful improvements in switch-stands, as will behereinafter more fully set forth, and pointed out in the claims. c p

The object of this invention, which is applied to switch-stands having a closed base, is to afford a means whereby the bolt which i connectsthe operating-lever and connectingrod will be prevented from being displaced, if the same should break during the passage of a train, or at other times,an d to provide ameans whereby the bolt can be removed and anew one vinserted without taking up or removing the frame of the switch-stand.

In the ordinary form of switch-stands, the bases of which are closed, it has been necessary to insert the bolt in the hole provided for it in the connecting-rod and operating-lever before the stand is secured in place, and when this connecting-bolt becomesworn `or broken it `is necessary to remove the frame of the stand in order to insert a new one. My invention is designed to overcome this diffculty.

In theanneXed drawings,`which illustrate my invention, Figure 1 is a side view of an ordinary switch-stand, showing my invention applied thereto. Fig. 2 is a vertical trans ierse section taken through' the line as x of 1g. l. 'c Y.

A represents a switch-stand, B the connect- `ing-rod, and C the operating hand-lever,

which is pivoted to the center of the frame A, which is provided with locking means at .its upper end. The lower portion of this switchstand 'his made solid or closed, the only open'- the dovetailed slot formed therein.

ing being for the passage of the connectingi rod B and operating-lever C. The lower portion of this switch-stand isprovided with side walls, A', which completely inelose the lower part of the same. 'Ihese side walls may be provided at their lower` portion with flanged bases a a. One of these side walls is provided with an opening, b, which registers with the lower end of the lever C at some point of its movement, 'which opening is providedwith a sliding door, I), this sliding door being let into and secured to the side wall in a dovetailed slot, the sides of the door being wedge-shaped, or angular, to correspond with At asuitable point above the opening b is a perforation through which passes a bolt, which also passes through a slot in the sliding door, by means of which bolt the door is secured against displacement. By this arrangement the inner sides of the side walls have asmooth surface, as the door does not project beyond the same, and the head and point of the bolt which connects the conneeting-rod and operating-lever may bear against the same without impeding the operation of the lever. It will also be seen that if the bolt which connects the parts hereinbefore mentioned is broken the same cannot become displaced nor fallout of place, as the side walls will prevent such displacement, and as soon as the break is discovered the old bolt may be removed and a new one inserted through the opening in the sideplates.

To a switchstand not provided with closed sides a plate having an angular projecting at its base may be attached, or iu position upon the base thereof, so as to bear upon the head of the connecting-bolt and prevent the same from` being displaced, in which cases said auxiliary side vis provided with an opening or door, as hereinbefore described.

Having thus described my invention, what I` claim as new, and desire to secure by Letters Patent, is-

Incombinatiou with a switch-stand having a closed base, the side wall, A', having` an opening therein at a point to correspond with the connectingpoint of the switch-rod and operating-lever, and a flanged base, a, substantiaily as shown7 and for the purpose setl taehed to one of the side walls, Substantially 1o forth. 1 y as shown, and for the purpose set forth. 2.
